Cook the fruit and liqueurs on HIGH for five minutes in the microwave. (Joanna cunningly uses a round glass dish about eight inches wide and four inches deep -- 20x10cm -- and also cooks the cake in it.)
Add the butter and spices. Tip this mixture into a large basin and stir in the rest of the ingredients.
Line the glass dish with baking paper, pour in the ingredients, cook on HIGH for 15 minutes, elevating the dish while cooking, for example by sitting it on a small upturned china dish.
Test with a skewer. (When the skewer comes out clean, the cake is cooked.)
Allow the cake to cool before removing from the container. You can simply remove the baking paper and the put the cake back in the dish it was cooked in, put the lid on and store in the fridge. How's that for simplicity!
